The universe is full
the unknown and
Every experiment holds
the chance of success
or failure, vindication
or complete confusion.
The truth hides itself
in dark matter, unseen
and barely theorized.
Black holes swallow light
and allow no answers to escape.
Matter squeezes itself
into singularities --
impossible, yet it is so.
No matter how much you know,
most of science remains in the shadows,
like an iceberg lurking below the waves.
Mostly we find it by running into it
and sinking our whole worldview.

Dark matter is unobserved stuff that holds the galaxy together.
Black holes may be thought of as pits or tunnels in spacetime. It is debated whether any, some, or all of them are connected to some other location where they emit what they suck in.
Singularities are gravitational pinpoints of existence.
Icebergs are famous for showing only a sliver of their mass, with most of it hidden underwater. What you know is always a lot less than what you don't know.
